Nates-Substack-Skills

Recognize and capture reusable patterns, workflows, and domain knowledge from work sessions into new skills. Use when completing tasks that involve novel approaches repeated 2+ times, synthesizing complex domain knowledge across conversations, discovering effective reasoning patterns, or developing workflow optimizations. Optimizes for high context window ROI by identifying patterns that will save 500+ tokens per reuse across 10+ future uses.

Active diagnostic tool for analyzing skill prompts to identify token waste, anti-patterns, trigger issues, and optimization opportunities. Use when reviewing skill prompts, debugging why skills aren't triggering, optimizing token usage, or preparing skills for publication. Provides specific, actionable suggestions with examples.

Debug, diagnose, and troubleshoot skill issues including trigger failures, parameter problems, prompt conflicts, and SKILL.md structural issues. Use when skills don't activate as expected, trigger incorrectly, produce unexpected behavior, conflict with system instructions, or fail packaging validation. Analyzes YAML frontmatter, descriptions, progressive disclosure, token budget, absolute statements, and reference file organization. For skill creators reviewing, validating, or fixing skill problems.

Analyzes skill ecosystem to visualize dependencies, identify workflow bottlenecks, and recommend optimal skill stacks. Use when asked about skill combinations, workflow optimization, bottleneck identification, or which skills work together. Triggers include phrases like "which skills work together", "skill dependencies", "workflow bottlenecks", "optimal skill stack", or "recommend skills for".

Auto-generates standardized README documentation from SKILL.md files, validates consistency (frontmatter, descriptions, terminology), and creates usage examples. Use when documenting individual skills, generating docs for multiple skills in a directory, or validating skill quality standards.

Analyzes the user's skill library to identify coverage gaps, redundant overlaps, and optimization opportunities. Use when users want to understand their skill ecosystem, optimize their skill collection, find missing capabilities for common workflows, or reduce redundant coverage. Triggered by requests like "analyze my skills," "what skills am I missing," "are any of my skills redundant," or "optimize my skill library."

Analyzes skill usage patterns across conversations to track token consumption, identify heavy vs. lightweight skills, measure invocation frequency, detect co-occurrence patterns, and suggest consolidation opportunities. Use when the user asks to analyze skill performance, optimize skill usage, identify token-heavy skills, find consolidation opportunities, or review skill metrics.

Comprehensive security risk analysis for Claude skills. Use when asked to analyze security risks, review security stance, audit skills for vulnerabilities, check security before deployment, or evaluate safety of skill files. Triggers include "analyze security," "security risks," "security audit," "security review," "is this skill safe," or "check for vulnerabilities."

Provides test cases and validation tools for skills. Use when creating tests for a new skill, adding regression tests after skill updates, running test suites to verify skill functionality, or validating that skill outputs match expected results. Supports unit tests, integration tests, and regression tests with input/output pair validation.

Proactive token budget assessment and task chunking strategy. Use this skill when queries involve multiple large file uploads, requests for comprehensive multi-document analysis, complex multi-step workflows with heavy research (10+ tool calls), phrases like "complete analysis", "full audit", "thorough review", "deep dive", or tasks combining extensive research with large output artifacts. This skill helps assess token consumption risk early and recommend chunking strategies before beginning work.

Conversational guidance for building software with AI agents, covering workflows, tool selection, prompt strategies, parallel agent management, and best practices based on real-world high-volume agentic development experience. Use this skill when users ask about setting up agentic workflows, choosing models, optimizing prompts, managing parallel agents, or improving agent output quality.

Comprehensive framework for evaluating AI vendors and solutions to avoid costly mistakes. Use this skill when assessing AI vendor proposals, conducting due diligence, evaluating contracts, comparing vendors, or making build-vs-buy decisions. Helps identify red flags, assess pricing models, evaluate technical capabilities, and conduct structured vendor comparisons.

Comprehensive toolkit for creating multi-tab Excel workbooks for startups and scale-ups. Use this skill when building financial models, operational dashboards, board reports, or analytics workbooks that require data organization, complex calculations, pivot tables, visualizations, and documentation across multiple interconnected sheets. Specialized for startup metrics (ARR, MRR, CAC, LTV), board-level reporting, and data-driven decision making.

Comprehensive job search strategy skill for analyzing job postings, discovering non-obvious insights, conducting conversational skills-matching interviews, identifying skill development needs, and creating creative, personalized application strategies. This skill should be used when users want help with job applications, career transitions, analyzing job opportunities, or developing targeted job search approaches that help them stand out from other candidates.

Comprehensive pitch deck creation with conversational discovery, narrative structuring, and context-aware chunking strategies. This skill should be used when users request help creating pitch decks, investor presentations, fundraising decks, or startup presentations. It guides through narrative development, data collection, and professional slide creation.

Comprehensive library of proven prompting patterns, frameworks, and examples for different use cases. This skill should be used when creating prompting guides, analyzing prompt effectiveness, teaching prompting techniques, or troubleshooting prompting issues. Use when writing about prompting, explaining prompting concepts to others, or improving existing prompts.

Systematic framework for analyzing product documents (PRDs, feature specs, user stories, roadmaps, one-pagers) to identify gaps, generate clarifying questions for PMs and engineers, and assess technical risks. This skill should be used when engineers or technical leads need to bridge PM documents and implementation by eliciting missing technical details rather than making assumptions. Use when asked to extract technical requirements, review specs, identify what's missing, or prepare clarifying questions from product documents.

Comprehensive resume creation, review, and optimization with support for multiple formats, ATS optimization, industry-specific guidance, and career stage customization. Use this skill when users request help writing, creating, reviewing, improving, or tailoring resumes for job applications.

Comprehensive guide for AI-assisted vibe coding. Use when the user wants to build applications through natural language prompts using tools like Lovable, Cursor, Replit, or Bolt. Includes best practices, pitfall awareness, tool-specific guidance, architectural decision support, and MVP scope definition with a bias toward cutting features aggressively to ship faster.

Specialized guidance for editing EXISTING Excel files with emphasis on preserving formulas, formatting, and structure across multiple tabs. Use this skill when modifying, updating, or adding data to existing .xlsx files where maintaining integrity is critical—particularly for multi-tab workbooks, complex formulas, formatted tables, and data that must maintain sort order and relationships across sheets.
